摘　　要：虚拟仪器技术是现代计算机系统和仪器系统相结合的产物,是当今计算机辅助测试领域的一项重要技术,它推动着传统仪器朝着数字化,智能化,模块化,网络化的方向发展。目前在大型变压器的损坏事故中,绝大部分是由于在外部短路电流的冲击下,使变压器绕组产生严重变形所引起。因此在变压器遭受外部故障电流冲击后,有必要立即对其绕组的变形情况进行检测。本文简要介绍了测量变压器绕组变形的频响法和电抗法的基本原理,着重介绍了基于LabVIEW的变压器绕组变形测试仪开发的基本过程。Virtue instrument is the combination of computer and instrument system. As an important technology in computer aided test,the virtue instrument promotes traditional instruments develop toward digit,intelligent,modular and network. At present,most transformer accidents caused by transformer windings which is the result of short-circuit current impulse. Therefore,it is necessary to detect windings after current impulse. The paper introduced principles of frequency response method and reactance,especially development of textured tester of transformer windings based on LabVIEW.
